For years, geologists suspected there were faults beneath the surface of the land of southeastern Colorado and across the state lin in Northeast New Mexico.  Then fracking came to the area, as natural gas was extracted and waste waters were stored deep underground.  Following that, starting in 2001 the Raton Basin was hit by a series of small earthquakes.  Geophysicist Jenny Nakai of the University of Colorado, Boulder connects the dots and explains the mechanics of the connection between deep storage of waste water and earthquakes expected to grow in number and amplitude.
